What a plan for a blue water boat ? No fuel sloshing around the dirt in the bottom of the tank. The engine pulling in this dirt and stopping just when it is needed the most. I see possibility for the future ? Change the limitations ?
Good day, Lou
The larger issue, after the batteries, is re-charging them. Most offshore cruisers struggle to re-charge the house bank enough for day to day needs, often running the engine to help the solar and wind systems. Once you add a largish 48 volt bank for propulsion it becomes unmanageable.
We're not there yet.
Daysailing with the occasional overnight cruise and plugging in to re-charge at the home marina is about where it is now.
